Ivory has 12 stickers fewer than Xylia but 32 stickers more than Ken. The three children have 268 stickers altogether.
- How many stickers does Ken have?
- How many stickers does Xylia have?
(a)
Number of stickers Xylia has = 1 u
Number of stickers Ivory has = 1 u - 12
Number of stickers Ken has = 1 u - 12 - 32 = 1 u - 44
Total number of stickers
= 1 u + 1 u - 12 + 1 u - 44
= 3 u - 56
3 u - 56 = 268
3 u = 268 + 56
3 u = 324
1 u = 324 ÷ 3 = 108
Number of stickers that Ken has
= 1 u - 44
= 108 - 44
= 64
(b)
Number of stickers that Xylia has
= 1 u
= 108
Answer(s): (a) 64; (b) 108
